Chartering a collaborative project

In the solitary working life of a freelance library and archive conservator, there sometimes comes along a project that provides you with a welcome opportunity to collaborate closely with other conservation professionals as well as the client to ensure a really sound outcome. A recent project to conserve, digitise and rehouse two mid-C16th parchment foundation charters was such an opportunity, with some impressive results.

 

 

 

 

The larger 1562 foundation charter                                  The smaller 1551 charter

The charters had been displayed and stored in standard frames with minimal preparation or secure mounting. Consequently, they had not only retained their fold creases and damage from their previous storage but had also slipped down in the frames.

They had previously been displayed in an office environment where conditions were understandably more suitable for human comfort than housing parchment charters. Despite this, and given their age, they were in an acceptable condition. The larger, 1562 charter had lost its great seal and black seal cord, and the heavily applied header ink was cracked with some losses, commensurate with the storage environment and repeated folding and refolding. The smaller, earlier 1551 charter had been extensively water damaged at some stage, and this had resulted in extensive planar distortions and what looked like a loss on its left edge. Both had plenty of ingrained and surface dirt – but some grubbiness after 450 years is to be expected.

The clients’ aim for the conservation of the charters was two-fold: to be good custodians of these key archive items in their institutional story and to provide a means of protecting them for the use and enjoyment of future generations. In discussion with the client, I suggested that the permanent housing could also be a very suitable means of display. Using the example of a Perspex fronted boxed display mount I created for a C13th charter, part of an Oxford college collection, I showed that the charters could be stored and displayed in attractive permanent mounts which allowed full access to the objects whilst offering a high level of protection. Additionally, the two layers of housing – the box mounts and the storage box itself – would act as a buffer against environmental fluctuations, inevitable where storage conditions are unregulated or primarily for human comfort. It was also decided that digitisation of the charters would provide a flexible and safe means of accessing their potential for teaching and research as well as wider institutional interest.

Once out of the frames the charters were lightly cleaned to remove the loose surface dirt. This was approached cautiously, due to the friability of the media of the larger charter in particular. They then spent several weeks between felts and under weights to encourage the most severe folds and distortions to relax and flatten down. This meant that minimal humidification could be employed to remove the most persistent creases. Controlled drying techniques using pinned bulldog clips to tension the minimally humidified parchment as it dried were used to remove the planar distortions.

After flattening came repair, with the welcome discovery that the damage to the left edge of the 1551 charter had resulted in very little loss, and most of the torn area once flattened could be returned to its original position.

Now we come to the collaborative part of the process. Working closely with library and archive digital photographer Colin Dunn of Scriptura the conserved charters were imaged at a high resolution to produce a faithful digital copy for archiving and facsimile reproduction as well as lower resolution images for use online. I was able to transport and handle the charters safely on behalf of the client and return the items to the studio within a day. After digitisation, my final task was to strap the conserved, digitised charters to individual bifold mounts with inert polypropylene strapping, secured on the verso of the mount with Tyvek tape. The charters themselves were not hinged or permanently secured in any way, and the strapping could easily be removed if it was necessary to take the charters out of their mounts.

The final stage of the project was the construction of the box mounts and the storage box for the mounted charters. My design was based on each mounted charter being stored and displayed in individual Perspex fronted hinged box mounts with a paper covered plastazote frame to give the necessary height. The two box mounts would slot into a specially designed presentation box which could safely and securely accommodate both charters, with the smaller charter recessed into a step in the base of the box and the larger and more frequently used charter on the top. Here effective collaboration was essential, as the measurements had to be exact to ensure a good fit for all the components with no movement during storage or transportation.

Originally specialist box and mount maker Bridget Mitchell of Arca Preservation was going to create the outer presentation archive storage box only but given the need for exact measurement required it made sense for her to create the box mounts too. The impressive results wholly vindicate this decision, and are an effective demonstration that the sum can be equally good as the parts in a complex project where many talents come together to create the best outcome for the object and the client.

       

    

  

Cut Threads and Fancy Weaves

There has been quite a gap between this and my last blog post, mainly due to end of academic financial year deadlines and several extended on-site projects. So by way of compensation for my neglect of my blog, I bring you a collection that is full of colour, texture and variety.

I was very fortunate to assess the conservation and collections care potential of the pattern book archive at The Silk Museum in Macclesfield earlier this year, mainly with the aim of making ongoing housing and storage recommendations for this wonderful collection of impressively proportioned books.

Macclesfield was the centre of silk manufacture from the late eighteenth century. The current museum is very appropriately housed in the original School of Art building where the designers for the silk products were educated from the late 1800s until the silk industry declined in the mid twentieth century, as people no longer wore silk goods such as headscarves or, with the advent of synthetic materials, used silk for parachutes, handkerchiefs or ties to such an extent.

The pattern book archive is an incredible record of a lost industry’s heyday: each book is full of textile samples and intricate painted designs, and demonstrates a surprising love of vivid colour and in some cases fairly outlandish patterns during the Victorian era.

 

 

 

 

 

 

 

Each book is a classic stationery binding, constructed to withstand fairly vigorous use and handling, and looking through them is an journey into a highly imaginative taste and style.

 

 

 

 

 

 

The extent of the pattern book collection – there are over 900 volumes – and each volume’s weight due to their elephant folio size presented a significant challenge to find a housing solution that was protective but would not substantially add to the weight or the bulk of the volumes, space being limited in the repository. This ruled out boxing, even before the financial implications of rehousing over 900 volumes came into consideration. The solution was Tyvek, a wonderfully versatile material made from inert polyester that is resistant to tearing but provides an excellent protective barrier to handling damage and dust. This is easy for the volunteers working to support the care of the archive to fit and replace, and make each volume more contained and easier to handle for use in research.

I look forward to posting more when the work to rehouse the collection is complete.

 

Many thanks to the Silk Museum for allowing me to post these images.

Access all areas

Conservation is rarely undertaken without future use being the driving force. It is usually dictated by the need to access the information an object contains, but being prevented from doing so by its overall poor condition or the stability of individual components such as the sewing structure or the media. The first question I ask when assessing objects for conservation is often

How will the item or collection be used?

The treatment is guided by the response, with different approaches being taken for say, stabilisation for cataloguing and digitisation or extended term storage with occasional future use to an object that will be regularly handled or is scheduled for display. But in the end it all comes down to conservation being the means of improving access to an object. 

 

 

 

 

 

This was certainly the case for an impressive archive item from the St Bartholomew’s Hospital collections that has just been conserved. Measuring almost a metre in height and over a metre in width and dated 1867, this tracing paper plan of the hospital’s laboratory equipment is a wonderfully evocative object, showing the inner workings of a state of the art hospital, nineteenth century style. Detailing autoclave cauldrons, mechanised stirrers, twisted pipework and complex pulley and winch mechanisms, the delicate accuracy of the ink and possibly watercolour drawing was remarkable. Perhaps it was created to introduce or promote a model for modern hospital practice at the time but in 2018 looks quaintly archaic and more than a little steampunk.

 

 

 

 

 

 

Use and storage over the intervening 150 years had taken its toll, with the object now in two main sections and several loosely attached or detached sections around the edges.  The surface dirt accumulations on the exposed surfaces of the object were also problematic for safe handling, with cross contamination being a significant risk. At some stage it was backed with stiff, thick wove paper and rolled. It is probably this rolling that caused the main tear up the length of the object, as the edge peaked and tore as it was being unrolled. Some of the original tracing paper had chipped away from the torn edges, showing the much lighter backing paper behind to high visual contrast with the darker toned tracing paper. This backing, although less than ideal and overly sturdy for the object, has probably saved the very fragile tracing itself. The fierce curl that the relatively more rigid backing had created from being rolled meant that the tracing could not be handled safely and as such was unable to be used for research or display.

Tracing paper is extremely sensitive to moisture, so lengthy humidification to flatten was not an option. After an extended period of weighting to reduce the curl, minimal humidification was able to be used to flatten the object almost completely. Unobtrusive conservation using very thin strips of toned Japanese paper on the recto and naturally coloured on the verso has reduced the aesthetic impact of the backing below. This and supported storage in a melinex sleeve in a board folder has allowed the full joy of this object to be revealed, restoring its status as being in a fit state for production for use and research once more.

Digging the dirt

Although the primary aim at the outset of any conservation project is to stabilise and prolong the life of existing structures and formats, sometimes this is not possible and the need for safe access to the information they contain has to be given precedence. This remarkably shaped object certainly fell into this category.

This early C20th stationery binding contained bundles of correspondence in envelopes which had been adhered directly onto the leaves. Over time, the binding structure had become distorted from the thickness and number of inserted items attached to the textblock, resulting in this dramatically mis-shapen spine profile and ultimately the detached (and unfortunately lost) upper board. It must have seemed like a good solution at the time to use the envelopes as pockets to store the sheets of correspondence but ultimately  this proved to be the death of the binding as a functioning housing method. In this case, the access to and safe handling and storage of the correspondence had to take precedence over the damaged binding.

The  physical bulk of the inserts had also allowed extensive dirt deposits to accumulate on all the leaves – it was quite possibly the most consistently dirt-affected object I have come across. There was also browning and embrittlement of the edges of the leaves, again an effect of exposure to dirt and an unfavourable historic storage environment. This, and the weight of the envelope inserts, had caused extensive edge tears and chipping throughout the textblock. The information could not be accessed safely by the Librarian or readers, and the risk of the loose surface dirt affecting the largely clean documents in the envelopes was high. A decision was made in consultation with the Librarian to remove the correspondence bundles from the envelopes and house them separately from the binding. Whilst not ideal, this would provide safer access to the information, cut down on handling and allow an economic treatment solution.

The first stage was to clean every page and inserted item thoroughly, and the positive results of this can be easily seen below.

As most of the inserts were folded, flattening was required. Due to the nature of the inks used and the quantity of the sheets it was not desirable or feasible to use humidity to encourage the sheets to relax and flatten. Therefore, the inserts were unfolded and weighted between blotters over a period of time, with excellent results.

The flattened inserts were then rehoused in folders in boxes, allowing easy access to the information without the risk of damage to the correspondence collection. The binding and textblock were also stored in a box to maintain the record of their previous housing format.
